Abstract
The invention discloses a hub motor with built-in silencing gaskets, comprising a rotor, a stator, and a core steel frame. The rotor coats the stator. The core steel frame is arranged in the center of the stator. The inner ring surface of the stator is provided with a core and an armature winding. The core and the core steel frame are connected and fixed together. The outer end face of the core steel frame is provided with a concave groove, multiple silencing gaskets are embedded into the concave groove, and the outer sides of the multiple silencing gaskets are coated with reflective paint. Through the scheme, the hub motor of an electric vehicle can be silenced and noise-reduced, so that the motor runs more softly in the driving process of the electric vehicle. The silencing gaskets protruding from the hub motor are coated with reflective paint, which plays a warning role.
Description
Technical field
The present invention relates to machine field, particularly relate to the wheel hub motor of a kind of built-in noise reduction pad.

Wheel hub motor technology is also referred to as wheel inner electric machine technology, and power set, transmission device and brake apparatus are all integrated in wheel hub by its maximum feature exactly, is able to greatly simplified for the mechanical part of electric vehicle.But traditional motor runs all can produce certain noise, and general motor is simply by simply adding a cover cover plate by noise isolation, owing to having space and space in motor accessories so that noise can not get well processing, motor still has loud noise and produces when running.
Summary of the invention
The technical problem that present invention mainly solves is to provide the wheel hub motor of a kind of built-in noise reduction pad, it is possible to wheel hub electric motor of electric vehicle is carried out sound-deadening and noise-reducing process, and in allowing electric motor car travel, motor runs softr.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide the wheel hub motor of a kind of built-in noise reduction pad, including rotor, stator and iron core steelframe, described rotor is wrapped in outside described stator, described stator central authorities are located at by described iron core steelframe, inside described stator, circle face is provided with iron core and armature winding, it is connected fixing between described iron core with described iron core steelframe, Baltimore groove is offered in described iron core steelframe end face outside, described Baltimore groove is embedded in multiple noise reduction pad, and described silencing pad sheet lateral film face is coated with reflecting coating.
In a preferred embodiment of the present invention, described noise reduction pad is arranged in embedding described iron core steelframe, and described noise reduction pad two ends all protrude from described iron core steel frame plate face, and the end face of described noise reduction pad protruding end coats reflectorized material.
In a preferred embodiment of the present invention, described noise reduction pad offers multiple sound-absorbing honeycomb hole.
In a preferred embodiment of the present invention, described armature winding is wound on described iron core, and described iron core end face outside is fixing with described iron core steelframe to be connected.
The invention has the beneficial effects as follows: the present invention can carry out sound-deadening and noise-reducing process to wheel hub electric motor of electric vehicle, in allowing electric motor car travel, motor runs more soft, and wheel hub motor protrudes above and is coated with reflecting coating on the noise reduction pad of setting and can play warning function simultaneously.
